Just out of random I decided to check the PPM of the other two seedlings that are not in the cabinet. To my my most serious surprise the reading was over 1000ppm . Needless to say I took care of that pretty darn quick. I adjusted it to around 250ppm and rinsed the RW with the new water. They will be just fine but there is a lesson. The reason that the TDS was so high is actually elementary but over looked. These two seedling are still in a tray under a florescent. I feed them just by adding water to the try, but when the water dissolves the solids are still left behind. Ever time I added water the solids dissolved into the water raising the TDS. So I will keep that in mind from now on.
